SPECIFICATION forming part of Letters Patent No. 536,234, dated March 26, 1895.

Application filed August Ill., 1 8 94.

To all whom t may concern,.-

Be it known that I, WILLIAM C. SCHAPER,

of thecity of St. Louis, State of Missouri, have invented certain new and useful Improvements in Metallic Lathing, of which the following is a full, clear, and exact description,

/ reference being had to the accompanying ings of otherconstructions.

A'further object of my invention is to constructa lathing that will be especially eflicient in holding the mortar in place upon its face.

Referring to the drawings: Figure l is a plan View of a sectionof my improved metallic lathing. Fig. 2 is a sectional view onl the line2-2 of Fig. 1. Fig..3 is a sectional view on the line 3 3 of Fig. 1. Fig. 4` is a sectional view on the line 4 4 of Fig. 1. Fig. 5 is a sectional view on the line 5 5 of Fig. l. Fig. 6 is a plan Viewof a portion of a modified form of my improved metallic lathing. Fig. 7 is a sectional View on the line 7 7 of Fig. 6. Fig. 8 is a Sectional view on the line 8 8 of Fig. 6. Fig. 9 is alsectional viewvon the line 9 9 of Fig. 6.

Referring by numerals' to the accompanying drawings, 1 indicates the body or sheet of metal out of which the lathing is formed,A it being of suitablerthickness. The method of forming the corrugations, slits, lips, &c., in the sheetv metal body may vary, as various methods such as stamping, pressing, orpassing the sheet metal bodies through rollers specially formed will accomplish the desired result. y

The shaded portion, indicated by the numeral 2, is that portion that rests or engages directly against the rafters, boards, or to whatever the lathing is secured, and-may be properly termed the base of the lathing. This base 2 remains intact and occupies the plane originally occupied by the upwardly bent portions of lathing. At stated distances in the Serial No. 520,029. (No model.)

section l and extending in horizontal align- 'ment are pairs of upwardly projecting lips lor corrugations 3., the inner-faces of said corrugations being indicated by the numeral 4. The ends of these corrugations arerounded,

las indicated by the numeral 5, and in the rear of these corrugations at the point where they turn upward from the base l is'formed alongitudinal slit 6, the edge 7 of which is bent 'into a plane with that of the inner edges of the corrugations.

This will necessarily form depressions or valleys 8 in the longitudinal corrugations 3.

Strips 9 are preserved between the corrugavtions 3 and inV the same plane as the base 2. The portion 10 of the section 1 is bent into a plane approximately half way between that of the base 1 and of the upper inner edges4 of the corrugationsS.

In the formation ofthe corrugations in the section l, I have foundit desirable to alternate said corrugations'in their parallel lines,

though if desired said corrugatious may be formed in parallel lines in both directions.

In the portion l0 and between the pairs of alternated corrugat-ions 3 are triangular apertures 1l, the edges of which are bent in a vertical plane, or at right angles to the portion 10, said up-turned portions being indicated by the numeral V12.

In the modified form shown in Fig. 6, the strip 9 is dispensed with, the corrugations 3 being bent up from a centrally formed slit 13.

In the practical use of myimproved lathing, it is applied to the interior walls and ceiling of buildings as is ordinarily the practice, and Athe mortar applied directly thereto.

As said mortar is applied t'o my improved lathing, the same being plastic, will enter the space between the edges 4 of the lips or corrugations, and as pressure is applied to said mortar it will contact with the strip 9 and be delected in opposite directions thereby. By reason of this deliection, a portion of the mortar will engagek beneath the lips or corrugations 3 and when said mortar becomes hardened will be very firmly keyed or heldin position upon the lathing. Aportion of said mortar will also enter the slits beneath the `portions 7 and also through the triangular apertures 1l. Allthis, it Will be plainly seen, tendspto firmly position themortar in the IOO proper position upon the lathing and reduce the liability of the same becoming broken and disengaged therefrom to a minimum.

By bending the major portion of the section 1, or the portion indicated by the numeral l0, into a plane above the base portion, it will be seen how a lesser quantity of mortar is required to cover a given surface than if metallic latliing such as is commonly in use` be employed. It will also be seen how by bending the body of the section l into two differ ent planes or bases, the sections or bodies will be greatly increased in strength and lasting qualities.

ThusI have constructed a metallic lathing that possesses superior ad vaut-ages in pointof simplicity, durability and general efficiency.`

l. A metallic lathing having its body por tion bent into differential planes, and corru-` gations bent from the lowertnost plane up-` ward in such a manner that their inneredges face each other, said corrugations being provided with a slit and lip at the" juncture of the corrugation and the body portion.

2. A ,metallic lathing, consisting of a sheetl of metal having its body bent into `differential planes, alternating pairs ofcorrugaticns or lips bent upward from the lowermost` plane of the body portion, lips formed by slitting the rearof these corrugations, and triangular apertures, the edges of which are bent at right angles to the body portion, said triangular apertures being interspersed between alternating pairs of eorrugatons.

3. A metal latbing, consisting of a sheet of metal having its body bent into differential planes, pairs of lips or oorrugations bent from the lowermost plane in such a manner, as to leave a detlecting strip between said lips or corrugations, and lips formed by slitting the rear sides of the corrugations.

4. A metallic lathing, composed of a single sheet of metal, pairs of lips or corrugations having rounded ends bent upward from the body portion, a continuous corrugation or portion, such as l0, bent into a plane above the plane of theJ portion from which the lips orcorrugations are bent, and triangular apertures formed inlsaidicontinuous corrugation, the edges of said triangular apertures being bentat right angles to the continuous corrugation 10.

In testimony whereof I aix my signature in presenceof two witnesses.
